Patent GB-2045283-A (GB)
Title: Selective Solar Absorber
IPC: F24J2/46
Filed: 1980-01-24
Abstract: A selective solar absorber is obtained by forming a protected, graded, textured interface characterized by cavities of average depth D and of average spacing S, such that low reflectivity is achieved over a region of wave-length  lambda  ranging from 20S</=???</=6D. Outside these limits, the reflectivity substantially increases. A ratio of D/S of at least 7 provides a low reflectivity region of adequate width to contain the solar spectrum. The low reflectivity is substantially independent of incident angle of solar radiation. The absorber is made by vapour- depositing or sputtering reflective materials eg. Te, or metals and optical transparent materials such as glass. The interface is roughened by chemical etching or by ion bombardment.
Patent GB-2055006-A (GB)
Title: Multi Planar Camera
IPC: H04N11/00
Filed: 1978-08-25
Abstract: Television/photographic camera arrangement includes an optical arrangement which causes the image light from the camera's main lens system to be focused on two or more planes at different distances from the main lens system, e.g. for three such panes the resulting sub-images are arranged to include in-focus objects located in the far, middle and near distance ranges respectively from the main lens system. These sub-images are then analysed and the in-focus portions thereof selected and used to form a composite image which is substantially in-focus at all points. The sub-images are analysed by television cameras e.g. three colour television cameras, and the resulting video signals (specifically the luminance signals) are analysed e.g. by digital filtering, to determine those regions of each sub-image which are more in-focus than the corresponding regions of the other sub-images. From this in-focus determination a switching control signal is formed for selecting the in-focus video signals for transmission or recording. The in- focus selection may be effected by first recording the sub-image video signals on magnetic tapes and erasing the out-of focus portions. Cine or still photographic cameras may simultaneously record the sub- images and during the processing of the films those portions not in-focus are suppressed from each frame according to the compared television signals, the films then being combined to form a master film. Also described in an arrangement in which a single image is photographed or televised, and those regions which are determined to be out of focus e.g. by digital filtering, are mathematically enhanced under operator control to improve their sharpness so that they appear to be in focus.

Title: Fine liquid metal droplets from liquid or molten metal
Inventor: DIETZ PETER WILLIAM
IPC: B22D11/06
Filed: 1982-09-29
Abstract: Apparatus comprises a rotatable member 2 situated in a pressurized or evacuated chamber, means for generating an electric field at the edge of the member e.g. ring electrode 5 having sufficient strength to overcome the surface tension of the metal, and liquid metal delivery means 14 directing liquid metal onto a surface 3 of the member over which the metal flows toward the edge as the member is spun. As the liquid metal leaves the surface at the edge, the force of the electric field causes fine liquid metal droplets which are more uniform and smaller than those produced without an electric field to form. <IMAGE>

Title: Fuel briquette
Inventor: CASHMAN ROBERT GRAHAM
IPC: C10L5/44
Filed: 1982-11-08
Abstract: Fuel briquettes of high calorific value, which are clean and convenient to handle, are described. They are composed principally of paper and straw, preferably entirely of paper and straw. A suitable range for the dry weight content of the straw is 3 to 15%. Dye and/or an essence giving an attractive odour may be included. The briquette is formed by thoroughly mixing chopped straw with a paper pulp, shaping the mixture into the briquette, compressing it and then allowing it to dry. The presence of the straw assists the drying process because the straw leaves some air passages in the briquette.

Title: Pallet for holding a workpiece
Inventor: GARLEY ANTHONY MARK
IPC: D05B39/00
Filed: 1983-06-08
Abstract: A pallet for an automatic sewing machine has a work- receiving cavity (20) having re- entrant wall portions, and comprises a plate member (10) made up of three or more layers (12, 14, 16) laminated together. The cavity (20) is made up of separate cavities (22, 24, 26) formed in the various layers prior to their lamination together. The dimensions of the cavity (24) in the intermediate layer(s) (14) are larger than the other cavities (22, 26) so that the outer layers (12, 16) project beyond the cavity formed in the intermediate layer (14). The dimensions of the cavity (24) in the intermediate layer(s) (14) correspond to the dimensions of the workpiece to be held in the pallet. In this way, the workpiece can be "clipped" in the cavity (20). The dimensions of the cavity (26) in the lower outer layer (16) may be smaller than those of the cavity (22) of the upper outer layer (12), so that additional support is given to the edges of the workpiece beneath it while not impeding the insertion of the workpiece into the cavity (20). <IMAGE>

Patent GB-2142725-A (GB)
Title: Fluid flow meter
Inventor: HAMBLETT LAURENCE SIDNEY JAMES
IPC: G01F1/32
Filed: 1983-06-21
Abstract: A Karman vortex shedding flow meter for use with natural gas includes a Venturi. A bluff body (14) is located at the throat of the Venturi so causing vortices to spin off. An ultrasonic or optical detection device (15, 17) detects the vortices and the rate of gas flow is computed therefrom. The vortex shedding principle is only reliable at Reynolds numbers of 10,000 or more. By using the Venturi, the Reynolds number of the flow is temporarily increased, for instance by 30% or more, so allowing the low flow rates to be measured accurately. <IMAGE>

Abstract: A quick release, high torque coupling (16) between a bit (12) and a drive member (14) and consecutively disposed drive member sections in a mine roof drilling system has axial- locking section (44) and a torque- transmitting section (46) on its member ends. A plug (36) on the drive member (14) or drive member section is releasably received within a mating socket (34) in the bit (12) or connecting drive member section. The axial-locking section (44) is complementally configured with respect to an a circular constriction (38) in the socket to permit insertion of the axial-locking section into the socket beyond the constriction. The torque-transmitting section (46) cooperates with the constriction to limit relative rotation of the bit and drive member or interconnected drive member sections between oppositely directed torque-transmitting positions. In one of the torque-transmitting positions, the constriction and axial- locking section are misaligned such that the plug is restrained against axial retraction from the socket. <IMAGE>

Title: Telecommunication line circuit and associated voltage converter
Inventor: BIENSTMAN LUC ARMAND
IPC: H04M19/00
Filed: 1984-10-19
Abstract: A telecommunication line circuit includes line amplifiers LOAO and 1 which are connected to respective conductors TP and RG of a telecommunication line via feed resistances (R0, R1, Figure 1). A loop current measuring circuit SENC is coupled with the feed resistances and supplier signals to a resistance synthesis circuit LADC and impedance synthesis circuit LAAC the outputs of which are coupled back to the inputs of the line amplifiers. The resistance synthesis circuit is supplied with a signal VEET representative of line current by a circuit FDC (Figure 3) which has a controlled amplifier (OA4) and a resistance capacitance low-pass filter (R8, C1). The filter couples the measuring circuit to the controlled amplifier. Transistors (T3-T6) comprise a regulator which prevents sudden changes in the sensed line current from causing overshoot in the control signal (VEET) due to the time constant of the RC filter, by bypassing the resistor (R8) when the sensed current suddenly increases, and by short circuiting the capacitor when it suddenly decreases. <IMAGE>
